<P>
Note that this is a <STRONG>major new distribution</STRONG> and lots
of things have changed. Consult the <A HREF="hylafax4.0.html">general overview</A>
for a high-level description of the new functionality provided in the
v4.0 software.
<P>
This document describes the changes made to the software between the
<I>previous</I> and <I>current</I> versions (see above).
If you don't find something listed here, then it was not done in this
timeframe, or it was not considered important enough to be mentioned.

<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>
<UL>
<LI><B>configure</B> now recognizes when termiox support is present on
a system
<LI>a new <TT>CONFIG_SOCKARGLENTYPE</TT> parameter was added to specify
the type of certain length parameters in socket-related calls that
are defined to be other than <TT>int</TT> on certain systems
<LI>a bug was fixed that caused relative pathnames to be incorrectly
changed when gcc was to be used as the compiler
<LI>the file <TT><osfcn.h></TT> is now included only when it is
present on a system (on some systems it is not needed to compile
the software)
<LI>a new <TT>CONFIG_BADSELECTPROTO</TT> parameter was added to control
whether or not the <TT>select</TT> system call is assumed to take
<TT>int*</TT> parameters instead of <TT>fd_set*</TT> parameters
(this used to be assumed if the software was compiled under HP-UX
but with HP-UX 10.10 it apparently is no longer true)
<LI>a new <TT>UTMP</TT> parameter was added to control whether the
software should support the extended <B>utmpx</B> and <B>wtmpx</B>
files; possible values are: <TT>auto</TT> (configure based on the
existence of <B><utmpx.h></B>), <TT>utmp</TT> (normal usage), or
<TT>utmpx</TT> (extended usage)
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxq"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXQ:</B></A>
<UL>
<LI><EM><B>faxq</B> is no longer installed setuid fax;
it is assumed to be started by the root user</EM>
<LI>page chopping now keeps at least one inch of white space at the top of
each page to insure that there is room for any tag line
that might be imaged; this works around a limitation in the tag line
imaging support
<LI>pages truncated by page chopping now include one row of white space
at the bottom of the chopped page; this should help with fax machines
that force a margin at the bottom of each printed page
<LI>jobs blocked by concurrent activity to the same destination are
now queued sorted by their scheduling priority; this fixes a problem
where jobs to the same destination could be scheduled out of order if
they blocked due to concurrent activity
<LI>the maximum number of pages permitted in an outbound fax job is
now checked each time a job is scheduled; this insures that any
changes in this control are enforced even after a job has been
prepared for transmission
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxsend"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXSEND:</B></A>
<UL>
<LI>RTS/CTS flow control is now properly controlled on systems that
require termiox calls
<LI>the communication ID for each job is now reported in the server
trace log to make it easier to cross-reference the server log
to individual session logs
<LI>multi-strip TIFF images are now read entirely into memory before
they are transmitted; this avoids potential timing problems and
fixes a problem where page chopping that spans multiple strips
was not being done properly
<LI>a bug was fixed in the session logging support that caused an
extraneous ``m'' to sometimes appear in messages
<LI>a bug was fixed that caused the <B>pollrcvd</B> script to be
executed with high/realtime scheduling priority
<LI>session logging now specifies more clearly when ECM is used
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="pagesend"><B><FONT SIZE=+3>C</FONT>HANGES TO PAGESEND:</B></A>
<UL>
<LI>RTS/CTS flow control is now properly controlled on systems that
require termiox calls
<LI>the communication ID for each job is now included in the server
trace log to make it easier to cross-reference the server log
to individual session logs
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxgetty"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXGETTY:</B></A>
<UL>
<LI><EM><B>faxgetty</B> is no longer installed setuid fax;
it is assumed to be started by the root user</EM>
<LI>RTS/CTS flow control is now properly controlled on systems that
require termiox calls
<LI>a bug was fixed that caused certain queuer FIFO messages to overflow a
fixed-size buffer
<LI>a bug was fixed that caused the <B>faxrcvd</B> script to be
executed with high/realtime scheduling priority
<LI>ECM is now correctly enabled for receiving facsimile
in Class 2/2.0 modems
<LI>a bug was fixed that caused receive operations to prematurely
terminate when a Class 2.0 modem reported unacceptable copy quality
on a received page
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="hfaxd"><B><FONT SIZE=+3>C</FONT>HANGES TO HFAXD:</B></A>
<UL>
<LI>the SNPP <TT>SEND</TT> request no longer requires that a text message
have been specified
<LI>the SNPP <TT>MESS</TT> request no longer appends a newline character
to the specified text; to send a message with a newline character in
it the <TT>DATA</TT> request must be used
<LI>a bug was fixed that caused pathnames to files in the root to be
incorrectly processed
<LI>the text of the reply to the <TT>ALLO</TT> request was corrected
<LI>repeatedly setting the server in passive mode with the <TT>PASV</TT>
request no longer causes a new socket to be created each time
<LI>a bug was fixed that caused <B>hfaxd</B> to dump core when asked
to do certain operations on the default job
(e.g. ``<TT>JDELE DEFAULT</TT>'')
<LI><B>dev/socksys</B> is now created in the chroot'd spooling area
as needed; for SCO OS 5 systems that require this device to
implement <TT>setsockopt</TT>
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendfax"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDFAX:</B></A>
<UL>
<LI>a bug was fixed in the at-style time parsing code that caused
``now + 120 minutes'' to be incorrectly handled
<LI>a bug was fixed that that caused <B>sendfax</B> to dump core
on certain systems
<LI>a bug was fixed that caused certain errors to be reported without
a useful reason message
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="sendpage"><B><FONT SIZE=+3>C</FONT>HANGES TO SENDPAGE:</B></A>
<UL>
<LI>a new <TT>-n</TT> option was added for sending pages to numeric-only
paging devices; it suppresses the transmission of a text message
<LI>null text messages are no longer interpreted specially; to suppress
the transmission of text in a paging request the new <TT>-n</TT>
option must be used
<LI>a bug was fixed that caused send failures to report a null message
for the reason
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="faxmail"><B><FONT SIZE=+3>C</FONT>HANGES TO FAXMAIL:</B></A>
<UL>
<LI>jobs created through direct delivery are now submitted using the
identity of the user that invokes faxmail unless a new <TT>-u</TT>
option is specified on the command line
<LI><B>faxmail</B> now uses any Subject line to set the Regarding
field in an automatically generated cover page (if not otherwise
specified)
<LI><B>faxmail</B> now uses any To line to set the Receipient
field in an automatically generated cover page (if not otherwise
specified)
<LI>a bug was fixed that caused the default boundary marker to be
erroneously matched
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="misc"><B><FONT SIZE=+3>C</FONT>HANGES IN MISCELLANEOUS STUFF:</B></A>
<UL>
<LI><EM><B>faxqclean</B> is no longer installed setuid fax;
it is assumed to be started by the root user</EM>
<LI><B>faxabort</B> and <B>faxanswer</B> now require that
a modem be specified on the command line
<LI>a bug was fixed in the domain name mapping logic in <B>xferfaxstats</B>
<LI>the ZyXEL 2864 prototype configuration file now also matches the
ZyXEL Omni 288S modem which has a compatible command set
<LI><B>faxconfig</B> now properly recognizes when a trailing argument is
missing from the command line
<LI><B>faxstate</B> no longer dumps core when invoked without a <TT>-s</TT>
option
<LI>the value of the symbolic link created <B>tiff2fax</B> when no
document conversion is required was corrected
<LI><B>tiff2fax</B> now removes the target file before creating a symbolic
link to avoid problems with systems that do not automatically clobber
the target when it exists (and there is no controlling tty to prompt
for confirmation)
<LI><B>faxsetup</B> now arranges for <B>probemodem</B> and <B>faxaddmodem</B>
to use the <B>ondelay</B> program when probing the tty port to find out
the set of valid speeds; this fixes a problem found on certain
NCR systems
<LI>the advise given by <B>faxsetup</B> when encountering a COFF
<B>ps2fax.exe</B> executable on an IRIX 6.2 system has been corrected
<LI>a workaround was added to the string handling support to avoid
an ANSI C compilation botch in HP-UX
</UL>
<P><HR WIDTH=65% ALIGN=right>
<A NAME="html"><B><FONT SIZE=+3>C</FONT>HANGES IN THE HTML DOCUMENTATION:</B></A>
